General requirements
Equip the system with an expansion vessel to damp pressure rise due to volume changes
when the temperature varies. Equip the system with a pump that provides a nominal flow
and pressure. Keep the pressure within the limits specified in
Install a pressure regulator to make sure that the maximum permissible operating pressure
is not exceeded.
Install a bleed valve at the highest point of the cooling circuit, and a drain valve at the lowest
point.
The materials that can be used are listed in
Cooling circuit materials (page 86)
Coolant temperature control
The temperature of the coolant in the internal cooling circuit must be kept within the limits
specified in
. Note that the minimum temperature is dependent on
ambient temperature and relative humidity.
